The Riverwood Paneling Company makes two kinds of wood paneling, Colonial and Western. The company has developed the following nonlinear programming model to determine the optimal number of sheets of Colonial paneling (x) and Western paneling (x) to produce to maximize profit, subject to a labor constraint 14. maximize Z = $25x1-0.8イ+ 30x2-12x3 subject to + 2x2 40 hr. Determine the optimal solution to this nonlinear programming model using the method of Lagrange multipliers 15,
